Question 1

What are OBJ files?

Accepted Answer

Wavefront OBJ (.obj) is a widely supported text-based 3D mesh format. It can reference a material library (.mtl) which may reference texture image files.

Question 2

Can I load materials and textures?

Accepted Answer

Yes—drop your .obj together with its .mtl and any referenced texture images in the same drop. The viewer will resolve local references client-side.

Question 3

មាន files uploaded to manuals.plus?

Accepted Answer

Drag & drop and Browse loads are processed in your browser. If you load from a URL, your browser fetches that URL directly (subject to CORS).

Question 4

ហេតុអ្វី? URL loading fail sometimes?

Accepted Answer

Browsers enforce CORS. The host serving the .obj (and any .mtl/textures) must allow cross-origin requests (Access-Control-Allow-Origin).
